Dogs are animals kept for people’s companionship enjoyment or household benefits and not wild animals. Generally popular pets are best known for their loyal or playful characteristics, for their attractive appearance. Also generally known to provide their owners with important health benefits; keeping dogs is now medically recognized to help relieve stress for people who like having animals around. There are now special breeds of medically-approved dogs, "therapy animals," mostly dogs that are brought to visit confined humans. Also walking a dog can provide both the owner and the dog with exercise, fresh air, and social interaction.
